Abstract
Purpose
The purpose of this study was to examine hospital quality measures and the long-term functional outcomes associated with lateral compression type 1 [LC1] pelvic ring injuries.
Methods
A query was performed from December 2011 to September 2020 at two institutions within one hospital system for patients with a pelvic fracture diagnosis. Chart review was performed on admitted patients to determine demographic information, medical co-morbidities (to calculate Charlson Co-morbidity Index), in-hospital complications, length of stay [LOS], discharge disposition, and 30-day readmission rates. All patients included were treated nonoperatively. An attempt was made to contact all patients for long-term follow-up to assess current functional status with a Short Musculoskeletal Function Assessment [SMFA].
Results
Two-hundred and eighty-six patients were included, with 172 (65.9%) patients admitted and analyzed with respect to hospital quality measures. Patients admitted were older (83 vs 80 years, p = 0.015) with more medical co-morbidities (p = 0.001) than those discharged from the emergency department. The average LOS was 5.7 ± 3.7 days and 31 (18%) experienced in-hospital complications. The inpatient mortality rate was 1.2%, and the 30-day readmission rate was 8.1%. When comparing admitted patients without concomitant injuries, admitted patients with concomitant injuries, and non-admitted patients, admitted patients with concomitant injuries were found to have more medical co-morbidities (p = 0.001). Forty-three patients were available for long-term follow-up (average 36.6 ± 7.3 months), with an average SMFA score of 29.0 ± 25.7.
Conclusions
Patients admitted for LC1 pelvic fractures are likely to be older with more medical co-morbidities, and up to 1/5th will experience inpatient complications. Although inpatient mortality remains low, this injury pattern can lead to significant functional disability that persists for several years after injury.
